Answer:

cos0 = 6.8556546i/23 or sqrt-47/23

Step-by-step explanation:

hypotenuse is 23, opposite is 24

we have to find the adjacent using the pythagorean theorem

24^2 + b^2 = 23^2

576+b^2=529

subtract

b^2=-47

b=sqrt-47

sqrt of -47 is 6.8556546i, there is an i since it is the square root of a <em>negative</em>

cos = adjacent/hypotenuse
